Whenever driving slow through potholes or whatever un-evenness in say a driveway or dirt road I can see how much the frame flexes. On each side of the rear window I can see a section of the headache rack dip a good inch maybe close to 2" below the bottom of the rear window and the above the bottom of the window. So thats like a good 2- 3" of flex between the cab and my flatbed. That sound right?
I do have a dump bed so its hinged just behind the rear of the frame rail so I know that would amplify it but it seems like this thing flexes more that a lot of rigs I see. Does that sound normal?
